Left thoracic curve patterns and their association with disease

Area of Science:

• Orthopedics and Spine Surgery
• Pediatric Orthopedics
• Biomechanical Engineering

Background:

• The prevailing notion suggests left thoracic scoliosis is pathological, while right thoracic scoliosis is considered normal.
• This study investigates the association between the direction of scoliotic curves and the presence of underlying diseases.

Purpose of the Study:

• To examine the relationship between the lateralization (direction) of scoliotic curves and the existence of underlying pathology.
• To determine if scoliosis curve pattern is a reliable indicator of underlying disease.

Main Methods:

• Prospective analysis of clinical database material.
• Correlation of scoliosis configuration, patient gender, and diagnostic group.
• Interpretation of results within a biological framework.

Main Results:

• Congenital and infantile idiopathic scoliosis exhibited random right-left curve distribution.
• In older boys, left thoracic curves were more common and associated with underlying disease, but not strongly.
• In girls, early childhood onset and left thoracic patterns indicated disease, though right thoracic curves were most frequent overall.

Conclusions:

• While left thoracic curves correlate with disease, the association is not strong enough to guide diagnostic intensity.
• Scoliosis pattern alone is insufficient for differential investigation; clinical picture is paramount.
• Gender in males and age of onset in females are more significant risk factors than curve lateralization.
• All new scoliosis cases require thorough assessment, with advanced investigations based on the complete clinical context.
